Quality of ITR Tension Wheels
Our range includes a wide selection of tension wheels, from mini excavators to mining machines, ensuring high quality and performance. Starting from KUBOTA® K008 (with an operating weight of 0.9 tons) up to KOMATSU® D475 A5 (with an operating weight of 101 tons), we offer comprehensive solutions. Our engineering and R&D departments in Italy, South Korea, and China collaborate to combine expertise, technology, and development capabilities. Local engineering departments in each production plant have specialized knowledge of manufactured components, and the Italian Engineering headquarters coordinate all activities.
Functionality of ITR Tension Wheels
The function of the tension wheel is to properly tension and guide the track chain, ensuring its correct winding. The tension wheel and tensioner work together to maintain a specific degree of track tension. Efficient chain tension is a key factor affecting the durability of the undercarriage. The optimal sag for conventional tracks is about 50mm (+-5mm). For example, a track on an 80-horsepower machine with a 12mm sag will have a tension of 2540 kg when measured at the track tensioner. Meanwhile, the same machine, with the suggested 50mm sag, will have a tension of 362 kg. An overly tight track increases pressure, resulting in greater wear of the track bushing and drive wheel teeth, as well as the contact between the chain and the tension wheel and rollers. Appropriate tread hardness, equal to or greater than that of the chain links and running and support rollers, ensures impact resistance and balanced durability. Material: SCMn3A, hardening 50-55 HRC. Constant lubrication ensures minimal maintenance throughout its service life.
